Add precompilation workflows with PrecompileTools.jl

[MasonProtter]

A nice beginner task for someone looking to help out would be to use PrecompileTools.jl to speed up the TTFX of this package.

[kalmarek]

Based on tests I've created a precompiletools.jl with @compile_workload;

However I don't really see any speedup (in tests) since most of the time is spent in test_dataframes.jl etc. which we won't precompile.

should we pursuit this further?

in comparison:
with precompile_tools.jl:

julia> using Pkg; @time using BangBang; @time Pkg.test("BangBang"); @time Pkg.test("BangBang");

reports:

vs baseline:

Hm yeah I guess that makes sense. What happens if you dont include dataframes?

[kalmarek]

If I comment both zygote and dataframes tests take here

# with precompiletools
49.497205 seconds (670.57 k allocations: 66.080 MiB, 0.03% gc time)
28.202651 seconds (681.65 k allocations: 66.782 MiB, 0.06% gc time

# without
36.329705 seconds (682.08 k allocations: 66.775 MiB, 0.04% gc time, 0.01% compilation time)
33.570996 seconds (681.95 k allocations: 66.791 MiB)

Unless we find some nice (and useful) workload, I'd rather not do it due to much increased precompile times...
